Question

I’m building a webapplication in ASP.NET 4.0.

Now I don’t know the terminology for this, so it may be a stupid title and easy to find but I have tried to find a solution before posting here. But I really don’t know what this is called..?

Question:

How do I read variables from the URL?

Let’s say I type in

http://www.mysite.com/search/John/Doe

I want to take out “John” and “Doe” directly from the url, and set them as variables.

Also when visiting http://www.mysite.com, how do I add do so that the info in my textboxes add to the back one the url without reloading the page? But still processes my request?

If you are in asp.net 4 you can use Url Routing as follows;

In Globle.asax

void Application_Start(object sender, EventArgs e) 
{
        //define your route pattern here
        RouteTable.Routes.Add("SearchRoute", 
                    new Route("Search/{Firstname}/{Lastname}",
                    new PageRouteHandler("~/SearchPage.aspx")));
}

For http://www.mysite.com/search/John/Doe

In SearchPage.aspx

//access your route values here
string fName = RouteData.Values["Firstname"]; //John
string lName = RouteData.Values["Lastname"];  //Doe
